Abstract:
High-frequency percussive ventilation (HFPV) has been used for the management of patients with smoke inhalation injury for more than 20 years and is considered a standard of care at many burn centers. Because the ventilator is powered by air and oxygen rather than electricity, prehospital use has been limited by large-volume medical gas requirements. Since 2003, Operations Iraqi Freedom and Enduring Freedom have created a need for long-range aeromedical transfer of service members with severe burn and inhalation injuries. Unique to these conflicts is the availability of US Air Force C-17 cargo aircraft as the primary long-distance airframe. Because C-17 aircraft have a built-in medical oxygen supply, transcontinental patient transport using HFPV has become feasible. In this study, the authors report their initial experiences with the aeromedical transportation of 33 burn patients over a combined distance of 174,145 air miles using HFPV. HFPV is safe and efficacious for transcontinental flight when used by an experienced medical transport team.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...
